The owner of any parcel of land in the Town of Concord upon which a
building exists shall place the street address number assigned to that lot
on the front face of the building located closest to the street. The number
shall be affixed to the building in a prominent location facing and clearly
legible from the principal street. If the building is not visible or the number
not otherwise legible from the street, the number shall be permanently affixed
to a mail box, post, wall, sign or other permitted structure adjacent to the
entrance to the principal driveway serving the building. The number shall
be composed of Arabic numerals at least four inches high and in a color contrasting
with the color of the surface upon which they appear. The owner of a new building
shall comply with this chapter immediately upon completion of the siding or
the issuance of a certificate of occupancy, whichever shall first occur.
